Timeline

1926

Declan Costello (1 August 1926 – 6 June 2011) was an Irish judge, barrister and Fine Gael politician who served as President of the High Court from 1995 to 1998, a Judge of the High Court from 1977 to 1998 and Attorney General of Ireland from 1973 to 1977.

1943

He was educated at University College Dublin (UCD), where he studied Law and Economics from 1943, and was an auditor of the UCD Law Society.

1944

In 1944, he entered King's Inn on a scholarship.

During his time in UCD, he won a number of medals for debating in the Law Society and the Literary and Historical Society.

1946

His time as a student was interrupted in 1946 due to a bout of tuberculosis of the kidney which forced him to spend 10 months in a health clinic in Switzerland.

He survived the disease but at the cost of one of his kidneys, which would leave him in relative frail health and appearance for the rest of his life.

1947

Due to a relapse of his condition in 1947 that forced him to once again return to Switzerland, he missed his father's ascent to the office of Taoiseach in February 1948.

1948

In 1948, Costello completed his degree, joined the Irish Bar and began practising law in and around Dublin.

Having a family connection to the party, Costello had been a member of Fine Gael since joining college.

1950

Towards the end of the 1950s, Costello began to assert himself even more in Fine Gael; alongside a growing collection of progressives within the party, Costello founded a monthly political magazine as well as a research and study group focused on developing new policies for the party.

However, to their disappointment, Costello and his faction found the rest of Fine Gael slow and sluggish in response to their new ideas, and thought that they were against complex making of policies and the voicing of personal differences in public.

1951

He also served as a Teachta Dála (TD) for the Dublin North-West constituency from 1951 to 1969 and for the Dublin South-West constituency from 1973 to 1977.

The formulator of the Towards a Just Society policy document, Costello was credited with shifting Fine Gael towards the left, a move which made the party a more attractive coalition partner for the Labour Party.

Costello's ideals were later viewed as having been taken up by Garret FitzGerald, who became leader of Fine Gael and was twice Taoiseach.

As Attorney General, Costello created the Office of the Director of Public Prosecutions and the Law Reform Commission, and for this Costello has been called the "most consequential attorney general in the state's history".

David Declan Costello was born and grew up in Ballsbridge, Dublin, the son of John A. Costello who served as Taoiseach on two occasions, and Ida Mary Costello (O'Malley).

He attended the Sacred Heart convent school, Leeson Street, and St Xavier's School, Donnybrook.

In 1951, at the age of just 24, he was elected to Dáil Éireann as a Fine Gael TD for the Dublin North-West constituency during that year's general election.

He was the youngest member of the house at the time, earning him the informal title of Baby of the Dáil.

The following years would significantly influence Costello's political views; his exposure to the poor living conditions of his constituents in Dublin North-west radically altered his views on housing.

1953

In 1953, Costello married Joan Fitzsimons.

With Joan, Costello would go on to have four sons and two daughters.

One of these sons was later found to have autism, and the cause of children with special needs quickly became an area of special concern for Costello, particularly as "his elder brother Wilfrid had been left with a mild mental disability during birth".

1954

After the 1954 general election, John A. Costello became Taoiseach for a second time, while Declan retained his seat.

Although Declan was not placed in a cabinet position, he had a measure of influence over his father and the government.

Considered the most radical of those who advised his father, Declan pushed against the austerity measures of Finance Minister Gerard Sweetman, who in time would become a great rival and adversary.

1955

Costello co-founded the Association of Parents and Friends of Mentally Handicapped Children (renamed St Michael's House in later years) in 1955, and aided in the fund-raising for a daycare centre in 1956 for the education of children who were mentally disabled.

1956

Beginning in 1956 until he died in 2011, Costello was the St Michael's House president, making him ultimately responsible for 170 centres across the Dublin region.

1957

Following the 1957 Irish general election, in which Fine Gael and its coalition partners lost control of the government to Fianna Fáil, Costello became Fine Gael's spokesperson on foreign affairs.

In this capacity, Costello asserted liberal, anti-communist views while encouraging European integration amongst the growing European Economic Community organisation.

Two issues, in particular, drew his attention: the government's support for the withdrawal of Russian and US forces from Europe, and the support given for a resolution favouring the inclusion of People's Republic of China as part of the UN.

It was also at this time that he began to advocate that Fine Gael move politically leftward in order to broaden its image beyond that of simply being a status quo, bourgeois party, as well as to make it a more attractive coalition partner to the Labour party.

1959

Following his father's retirement from politics in 1959, longstanding member James Dillon became leader of the party and Costello felt his ability to influence policy-making slipping away.

1960

The fundraising would lead to the daycare centre becoming known as an official school in 1960.

1963

In 1963, Costello found an attempt to change party policy suppressed by the party leadership.

1964

Regardless, in April 1964 Costello broke party protocols and circulated a proposal to radically alter Fine Gael's economic policies.

At this point Costello did not expect his proposal to gain traction within the party; instead it was to be used as a pretext to leave the party and politics, and to turn to his work as a lawyer.

Costello neither canvassed other party members nor spoke to the press following the circulation of his document.

However, to his surprise, Costello's ideas began to pick up momentum with Fine Gael backbenchers, who had begun to crave a means by which Fine Gael could differentiate itself from Fianna Fáil.

Journalists too began to take an interest in the initiative, sensing a new direction emerging in Irish politics.
